What is a DID number?
A DID phone number is a virtual phone number that allows callers to directly communicate with a person or a specific department in an organization through a phone line. One of the most important advantages of a DID number is its high simultaneous call capacity. You can make any number of outgoing calls to people or departments of your organization for each incoming call to this number. For example, in the past, in organizations, each department or a person had their own phone number, and an operator had to control the calls and transfer them to the desired department. But today, by having a DID number and connecting it to your call center, you will have a space on the Internet that gives you high possibilities. This makes the process of making calls easier. It is also possible to mention the reduction of the time spent and the duration of the call queue. The system with which you can control your call center is called PBX for short.
